There's drag and drop support in streamtuner2 since 2.1.7, primarily meant for exporting individual stations into .XSPF or .PLS files, or dragging into audio players.

There is also support for exact XDND payloads. Most BSD/Linux desktop applications support little more than `STRING` or `text/uri-list` file dragging.  There's no standardization beyond that. Which is because nobody bothers to document anything. As exception to the rule:

The example payloads are abstracted here. The info ids are just Gtk-internal.

As said, only <kbd>text/uri-list</kbd> is used in practice.  It doesn't allow actual streaming URLs being transferred. Instead streamtuner2 has to create temporary export files. And since this dumb approach doesn't allow any content-negotation, a preconfigured default playlist format will be used for temp files. (Defaults to XSPF for crashing Rhythmbox.)

Alternatively there's <kbd>text/iri-list</kbd> now (yes, why not go with the century?) and <kbd>url/direct</kbd> to get a direct streaming URL/IRL.
